What is the difference between the NAMSR and the NAMSR Plus?
The NAMSR is ideally used to perform high-level queries, whereas the NAMSR Plus affords the user access to an increased volume and depth of data and hence greater flexibility in structuring queries of a more in-depth nature. To this end, the NAMSR has approximately 1.5 million records, while the NAMSR Plus has 39 million records. One consequence of the increased volume of data reported in the NAMSR Plus is that users should expect queries in this universe to take considerably longer than a similar query in the NAMSR.
